Today, I had planned on selling my PS3 that has gone mostly unused for a few months now. However, when I plugged it in, looking for a game that I believe is inside of it, the PS3 acts sort of funny. It's a PS3 Slim (can't remember capacity, was from the first run of them) The power light remains unlit, the power/eject buttons do nothing, no picture on the TV, and when I plug in the AC cord the fan turns on for about 15-20 seconds before shutting back off and beeping three times. No other results. What do?
